May not be. Although I haven't measured the amp drawn by 9gm servos, it appears from various sources that they draw somewhere in the range of 0.4-0.7amps. I feel an ESC with 3A BEC would be ideal, especially if you are going to do lot of aerobatics.

That depends on what servos they are?
If they are just nylon gear 9g servos, 4nos are fine with a 2A ESC.
for metal gear 9g servos, 2A is just right.
for standard servos you might need more than 2A even for just 2nos.
Though branded servos like corona and hitec draws little less than substandard counterparts.

If they dont bind or make any constant hissing noise then up to 5 servos(Up to my knowledge and i have used the same and tested. may be it can support more) are good to go with just 2A BEC if and only if the BEC can really supply 2A.(Some non branded ESC has BEC that wont really supply 2A but are rated 2A so beware)

Well the most easily available one is Sharma 10x6 and by far the best.  I am also using the same prop for a similar motor or you may use a 9x6 prop.  OK the best way to find a prop size is to contact Hobbyking on the live chat and ask for a product specialist to assist you in finding what is best suited for your  motor / ESC / model or whatever.  He also suggests the URL of items available with HK for your use. 

I often cross check it with him.
